Two San Gabriel Valley freeways are among the top candidates for a new toll lane project, according to a study released Tuesday by the Metropolitan Transportation Authority.

The MTA has been looking to expand a program that converts carpool lanes to High Occupancy Toll lanes.

The 57 Freeway between the 60 Freeway and the Orange County line was listed as a top candidate for a toll lane. So was the 10 Freeway between the 605 and the San Bernardino County line.

The other candidates include sections of the 91, the 405 and the 105 freeways.

“It doesn’t mean they are going to do these,” said Mark Littman, an MTA spokesman. “It’s a study to gather more information on where to go next.”

The study considered cost, commute-time savings, constructability and public perception.

The study follows an MTA HOT lane project on 28 miles of the 10 Freeway.

That project runs between downtown Los Angeles and the 605 Freeway. It started this year and is expected to be completed in 2012.

The toll on the 10 would vary depending on traffic. At rush hour the rate would be $1.40 per mile. For off-peak hours, the rate would be 25 cents per mile.

Cars with at least two people could still use the lanes for free. And no solo riders would be allowed if traffic in the lane was moving too slow. The lane would also be used by buses. The MTA is doing a similar project on the 110 Freeway.

The HOT lane project on the 10 was opposed by several San Gabriel Valley-area politicians, including county Supervisor Mike Antonovich, who thought the project was too rushed.

Officials hope the MTA will take more time to involve lawmakers in any projects that come from Tuesday’s report.

“It’s an interesting study,” said Antonovich’s transportation deputy, Michael Cano. “In our mindset its more theoretical at this point. We’re not opposed to the idea of toll lanes. But we’d like to see how the 10 corridor plays out first.”
